If you're treating an injured worker whose employer is self-insuring (SI), you should report the claim directly to that employer not BWC. SI employers are responsible for reporting the claim to BWC, and paying benefits and medical bills.

We've created an Excel spreadsheet with search capabilities that you can use to look up contact information for the SI employer, and then you can learn where to report the claim. Just follow the instructions below.
The same instructions are available on the actual spreadsheet.
